Vardy's contract with Leicester City ended over the summer, making him a free agent. He believes he can still play at a high level and is taking care of his physical health.
A source close to Vardy says he is eager to join Celtic and thinks he could be a valuable addition to the team. He enjoyed playing under Rodgers and hopes to reunite with him at Parkhead.
However, other clubs are also interested in signing Vardy, including Brentford and West Ham. It remains to be seen which team he will join by the end of August.
